Ingredients Equipment Method Notes

Ingredients
  

  • 6 cups frozen peach slices unthawed
  • 1 tablespoon granulated sugar optional, for the fruit
  • ½ teaspoon ground cinnamon for the fruit
  • 1 cup all-purpose flour
  • ¾ cup granulated sugar
  • ½ cup 1 stick unsalted butter, melted
  • 1 teaspoon ground cinnamon
  • Pinch of salt

Equipment

  • 8x8-inch ceramic or glass baking dish
  • Stainless steel mixing bowl
  • Whisk and fork (or pastry cutter)
  • Measuring cups and spoons
  • Wooden spoon
  • Aluminum foil
  • Oven mitts

Method
 

  1. Preheat oven to 375°F (190°C) and grease an 8x8-inch baking dish. Break up any frozen peach clumps and spread them in the dish.
  2. Toss the peaches with the optional sugar and cinnamon.
  3. Whisk together the flour, sugar, cinnamon, and salt, then stir in the melted butter until coarse crumbs form.
  4. Scatter the topping over the fruit and bake 40–45 minutes, until golden and bubbling.
  5. Rest 15 minutes before serving.

Notes

A heavy ceramic or tempered-glass baking dish gives the most even browning here, since it holds heat steadily while the frozen center thaws and cooks through. Whisk the shortbread topping in a sturdy stainless steel mixing bowl, and use a fork or a pastry cutter to work the melted unsalted butter into the flour for that signature sandy, crumbly texture. Keep a sheet of aluminum foil within reach for the foil-tent trick — loosely covering the dish in the final ten minutes protects the high-sugar crust from scorching while the peaches finish. A pair of quality silicone oven mitts makes pulling the bubbling dish out safely a non-issue. For leftovers, skip the microwave entirely: reheating in a countertop air fryer or a warm oven is the only way to bring the buttery crunch back to life, so store portions in shallow, airtight glass food storage containers that transfer straight from fridge to oven. If you're the type who bakes fruit desserts all winter long, a set of cup-for-cup measuring cups, a reliable oven thermometer for accurate temperatures, and stackable freezer-safe storage containers for stocking up on frozen peach slices will pay for themselves fast. Serve each warm portion with a generous scoop of vanilla bean ice cream — if you own an ice cream maker, a fresh homemade batch turns this simple weeknight crisp into a truly showstopping dessert.
